Description

Triangular section needle with spiral blades

Technical Field

The utility model belongs to the technical field of the acupuncture, concretely relates to triangle cross-section felting needle with spiral needle leaf.

Background

A needle machine is a blanket forming device for weaving a refractory fiber blanket blank with a certain thickness into a refractory fiber blanket through compaction and needle punching, a fiber web is repeatedly punctured by using a needle with a triangular or other-shaped cross section and a puncturing hook on an edge, the fiber web is crossly formed into a net or is arranged below an air-flow net forming machine, the fiber web is quite fluffy when being fed into the needle machine, a certain strong force is generated only by cohesive force between fibers, but the strong force is poor, when a plurality of needles puncture the fiber web, the fibers on the surface and the sub-surface of the fiber web can be driven by the puncturing hooks on the needle to move towards the vertical direction of the fiber web from the plane direction of the fiber web, so that the fibers are displaced up and down, and the fibers displaced up and down generate certain extrusion to the fiber web, so that the fibers in the fiber web are gathered and compressed.

When the needle reaches a certain depth, the needle begins to rise again, because of the forward direction of the needle, the displaced fiber is separated from the needle and is left in the fiber web in a nearly vertical state as if a plurality of fiber bundles are nailed into the fiber web, so that the compression generated by the fiber web can not be recovered.

The needle of the needle machine consists of four parts, namely a needle handle with an elbow, a needle waist (without the needle waist), a needle blade and a needle point, wherein the needle blade is a working section of the needle and is a main section of the needle, and the needle needs to be replaced frequently because the needle cannot adjust the size of the needle according to the size of a processed material when in use, but the needle is troublesome to detach.

SUMMERY OF THE UTILITY MODEL

To solve the problems set forth in the background art described above. The utility model provides a triangular cross section felting needle with spiral needle leaf has solved the felting needle and has dismantled trouble problem.

In order to achieve the above object, the utility model provides a following technical scheme: the triangular-section pricking pin with the spiral needle blade comprises a pin handle, a needle waist is installed on the right side of the pin handle, the needle blade is installed on the surface of the needle waist, a pricking hook is installed at one end of the needle blade, a hook groove is formed in the surface of the needle blade, and a needle point is installed at one end of the needle waist.

Preferably, the needle blade is spirally mounted on the surface of the needle waist.

Preferably, three barbed hooks are distributed on each needle leaf.

Preferably, the needle handle, the needle waist, the needle leaf, the needle point and the hook are all made of high-carbon steel.

Preferably, the surface of the needle handle is provided with a threaded column, a threaded groove is formed in the needle waist, and the threaded column is matched with the threaded groove box.

Compared with the prior art, the beneficial effects of the utility model are that:

1. when using, if the size of felting needle is improper, can twist and move the needle waist, make the threaded rod break away from the thread groove, make the needle waist take off from the needle handle, select the needle waist of suitable size, make thread groove threaded connection threaded rod, because the surface mounting of thread groove has the slipmat, prevent that the needle waist from landing when using, and easy operation, convenient to detach.

2. When the device moves upwards, the fiber can fall off from the hook groove, so that the fiber can move up and down, and the fiber which moves up and down can extrude the fiber web, so that the fiber in the fiber web is close to each other and compressed.

Drawings

The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification, illustrate embodiments of the invention, and together with the description serve to explain the invention and not to limit the invention. In the drawings:

fig. 1 is a side view of the present invention;

fig. 2 is a front view of the thread groove of the present invention;

fig. 3 is a side view of the present invention.

In the figure: 1, a needle handle; 2, needle waist; 3, needle leaves; 4, hook grooves; 5, needle tip; 6, hooking by a thorn; 7, a threaded column; 8 thread groove.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides the following technical solutions: triangular cross section felting needle with spiral needle leaf, including needle handle 1, needle waist 2 is installed on the right side of needle handle 1, needle leaf 3 is installed on the surface of needle waist 2, thorn hook 6 is installed to the one end of needle leaf 3, hook groove 4 has been seted up on the surface of needle leaf 3, needle point 5 is installed to the one end of needle waist 2, when using, the device moves down, make needle waist 2 pierce the fibre net through needle point 3, thorn hook 6 can hook some cellosilk and make its card in hook groove 4 simultaneously, and the downstream, when the device moves up, make the cellosilk drop from hook groove 4, make the fibre produce and shift from top to bottom, thereby let the fibre that produces the up-and-down shift produce certain extrusion to the fibre net, make the fibre in the fibre net draw close and compressed.

Specifically, the needle leaf 3 is spirally arranged on the surface of the needle waist 2, so that the moving distance of the cellosilk can be longer when the needle is used for puncture, and the working efficiency is improved.

Specifically, three barbed hooks 6 are distributed on each needle leaf 3, and the plurality of barbed hooks 6 can enable the cloth after puncturing to be smoother.

Specifically, the needle handle 1, the needle waist 2, the needle leaf 3, the needle point 5 and the barbed hook 6 are all made of high-carbon steel, the high-carbon steel is higher in hardness, good in wear resistance and low in cost, the use duration in the process can be prolonged during puncturing, and the heat generation in the puncturing process is reduced.

Specifically, the surface mounting of needle handle 1 has screw thread post 7, thread groove 8 has been seted up to the inside of needle waist 2, and screw thread post 7 agrees with 8 casees of thread groove, when using, if the size of felting needle is improper, can twist needle waist 2, make threaded rod 7 break away from thread groove 8, make needle waist 2 break away from needle handle 1, select suitable size needle waist 2, make 8 threaded connection threaded rod 7 of thread groove have the slipmat because the surface mounting of thread groove 8, prevent that needle waist 2 from sliding down when using, and easy operation, convenient to detach.

The utility model discloses a theory of operation and use flow: the utility model discloses after installing, the needle waist 2 of suitable size has been chosen, make its threaded connection on needle handle 1, when using, when the device moves down, thorn hook 6 can hook part cellosilk and make its card in hook groove 4 to be the screw-tupe lapse, when the device moved up, make cellosilk drop from hook groove 4, make the fibre produce and shift from top to bottom, thereby let the fibre that shifts from top to bottom produce certain extrusion to the fibre web, the fibre draws close and is compressed in the messenger's fibre web.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof.
